Hello Group, Several years ago I bought a QRPme Rockmite ][ kit to build but never got around to it.? Recently I pulled the kit out thinking to start the build but found that I do not have the

Replying to my own message. The Oscillator Fun kit is designed for audio frequencies. Is it possible we could have an Oscillator Fun kit that can be made for RF frequencies in the HF band as well? And

Hello fans of the can, What would be a good QRPme radio kit to build next? I built the Two Tinned Tunas EZ Build transmitter.? ? And I have a Sea Sprite+ transceiver kit ordered for the Buildathon

Group, Then I asked: what about one using torroids? and got: A low pass filter using toroids can also be designed for the 20 meter ham band. Toroids are a type of magnetic core that can be used to

group, Just asked a question of chatGBT. What is a good design for a low power low pass filter for the 20 meter ham band and got: A low pass filter is a circuit that allows low frequency signals to

Rex, Saw some doomsday predictions on the international state of affairs, esp China with population and workforce. Throw in a few wars and the shutdown of the Russian oil fields, which will take

I am starting building my Tuna Tunah as my 10W dummy load hasn't found too many signals across the pond. And by pond, I mean the one acre double pond at the treatment plant 100-feet to the north of me

Rex, We hope UPS lands their Santa sleigh successfully. A neighborhood had to be evacuated in N IL because the ice stretched out the guy wires of a commercial TV station that has fallen a couple of

I edited my original subject which creates a new topic. I wanted to correct the type of antenna. The antenna will not be a Zepp. The antenna will be an End Fed Half-Wave Antenna for 40 meter ham band.

Chuck, That is why I mentioned it. You cut off 17ft for the CP and the rest is the antenna. Nice way to give you both and not need a feed line. ---John AC9UV

Rex is including a counterpoise. There are No-Tune sources who are expecting coax to be the counterpoise. Connecting direct to the V6 kit cuts out feed line. Sent: Wednesday, February 22, 2023 4:18 PM

Based on feedback from Chuck, the antenna for the Sea Sprite+ with built-in No-Tune antenna coupler is designed to work with an EFHW (End Fed Half Wave) antenna.? ?The antenna included with the Sea

Daniel, I have only had the experience with the AD9850 DDS in making the VFO project. It went together well and has been a solid stable frequency source for my projects. Also in building various QRPMe

John, Very cool.? I want to home brew my own VFO.? I will eventually.? I have all the parts to build multiple VFOs using Si5351A (module or chip), LCD, rotary encoder, and a microcontroller (chips

John, This procedure works exactly as shown, the smaller the screwdriver the better. Actually, I had more of an issue putting it back together than I did taking it apart (as usual!). How to open and

Rex, Just got that nifty tool. I read the instructions but getting the cylinder out to clean seems to be stuck. Not wanting to force it. How is it best to do that. I thought of a screwdriver between

Oh, yeah--Daniel--? If you haven't tried 7055 kHz, most of the ops there don't go very fast--usually more than 5WPM, but I've heard 10WPM or slower, too. You don't have to stick to 7110-ish for speed

Daniel-- Short answer: Anything your license will support. Why? When I was a Novice (Tech +, actually, but still a novice operator), I loved the 40m Novice Band. It was years later, as a General or
